Can Anyone Help? Faint Line On Test....

I am new here, I needed some help on a picture we have of a test that my girlfriend did yesterday afternoon.

Now i have read loads of places that a "line is a line" and with being a bloke i aint that good with these kind of thing's lol We are kinda excited but do not want to build hopes up just incase its false! but i wanted to share the picture so we could have some feedback on what you guys think......

If you are reading this then Thankyou so much for taking your time to help us out.
